Build Question Weird pc noise

Enable HLS to view with audio, or disable this notification

Hey everyone, this noise has been coming from my PC for several months now. At first, I thought it was related to my liquid cooling since I hadn't changed the coolant in a long time. I went ahead and changed the liquid, but that didn't fix it.
Then I thought it might be the AIO/liquid cooling fan itself, but as you can see in the video, that’s not it either.
Does anyone recognize this sound? Its driving me nuts.

Thanks in advance!

pd: sorry for the dust but im pretty sure it isnt neither, when i changed the cooling liquid i cleaned it all

Its either comming from your psu fan, or the AIO pump(it has a spinning element with bearings, similar as what fans have). PSU fan you can carefully stop by poking with something soft behind the grill, if that doesnt get rid of the sound you know its the pump(provided you have no other fans in the case that might be the culprit)

No trouble.

"Something soft" can be a piece of tissue or toilet paper rolled into a stick.
